ok, i am having some issues with this setup.

after a long absence from the osx86 community i am trying once again to get my hp dv4000 working properly. so far things are going well. it is a 1.6ghz pentium m processor and i am running xnu 9.5 kernel with chameleon efi and intelenhanced speedstep.

the speedstep app shows all the available frequencies but i am unable to change them and if i select the fastest one, my system locks up.

the system clock seems to be running very fast and the seconds fly by at twice normal speed. i have tried booting with busratio=16 but it does nothing. using fsb=100 causes a kernel panic.

Hi,Pentium M is fully supported so it will work with a little tweaking.

First, I'm wondering where you read about the fsb flag? Because wherever I have mentioned it, I've made it clear that it is specified in Hz, not MHz When it panics, it prints out the busFreq and you could probably see it listed as 0.000100 MHz.

Second, which kernel are you using exactly? You can try uname -v in terminal.

Third, it should be sysctl machdep | grep EST, not hw.

Fourth, could you edit the kext's Info.plist file, and set DebugMessages to true. Then delete Extensions.mkext and reboot. Then you can see the kext's debug messages by using sudo dmesg | grep IntelEnhanced
